背景技术 Background technique

[0004]手动激活的注射器在市面上可得自多个制造商，包括本发明的拥有者及受让人，且用来藉肠道外注射投予药物溶液、药物悬浮液、疫苗、药物治疗、及任何其它液体药物。 [0004] Manual activation syringes are commercially available from a variety of manufacturers, including the owner and assignee of the present invention, and for administration by parenteral injection to a drug solution, a drug suspension, vaccines, medications, and any other liquid medication.此等注射器常由医事从业人员用来投予注射病人，但难以由自我投药病人使用。 Such a syringe Medical practitioners often administered injections to patients, but it is difficult to use by the patient self-administration.

[0005]自动注入器乃一种自动注射装置，设计来透过皮下针头将一剂药物投予病人，该注射通常由病人自身投予。 [0005] Automatic An automatic injector is the injection device designed to pass through a hypodermic needle to the drug administered to the patient, this injection is generally administered by the patient itself.自动注入器例如当病人激活该装置时自动地递送注射而发挥效用。 For example when the automatic injector automatically activating the delivery when the patient injection apparatus effective.此点与习知手动激活的注射器相反，于习知手动激活的注射器，病人本身需直接将柱塞按压入含药的筒身内来执行注射。 Within this point conventional syringes manually activated contrast, in the conventional manual activation of the syringe, patients themselves need to directly press the plunger into the barrel containing the drug injection performed.业已证实自动注入器特别可用来许可未受医事训练的使用者投予肠道外注射，且可提供心理上及肉体上的优势给病人。 It has been confirmed that the automatic injector can be used to particular user license were not trained Medical administered parenteral injection, and may provide a psychological and physical advantage to the patient.自1990年代第一支可重复使用的自动注入器问市以来，需要注射药物用于慢性病管理的病人已经使用自动注入器。 Since the 1990s automatic injector's first reusable asked the city, a patient needs injectable drugs for chronic disease management has been using an automatic injector.自动注入器提供对主要容器通常为预充式注射器的保护，且提供容易使用的溶液剂来供药物的自动注射。 Automatic injector provides an automatic injection of the primary container is usually protected by a prefilled syringe, easy to use and provides a solution to the drug supply.如此处使用，「自动注射器」及「自动注入器」等词指相同装置。 As used herein, "auto-injector" and "auto-injector" The words refer to the same device.

[0006]除了自动插入针头及剂量递送之外，有些自动注入器也结合安全机制来自动地保护病人免于在使用后接触针头。 [0006] In addition to the automatic insertion needle outside and dose delivery, automatic injector also incorporate some security mechanisms to automatically protect the patient from contact with the needle after use.先前技术的自动注入器通常设有针头罩，当致动时该针头罩延伸套住针头。 Prior art automatic injector is generally provided with a needle shield, the needle shield when the needle extends trap actuated.但此种安全机制可能无法致动及/或可能容易逆转，因而造成病人暴露于针头而容易遭致感染。 However, such security mechanisms may not be actuated and / or may be easily reversed, resulting in patient exposure to infected needles and easy stricken.此外，已知的自动注入器通常链接视觉、触觉、或听觉指示器至柱塞行程的末端或某些安全机制的致动，而非链接给药剂量的结束。 Furthermore, the known automatic injector link is generally visual, tactile, or audible indicator to the end of the stroke of the plunger or actuating some security mechanisms, rather than the link ends of the administered dose.因此，自我投药病人未被提供以一指示，指示药物已经完全递送而可去除针头，或者可能过早致动安全机制。 Thus, self-administration to a patient is not provided indication that the drug has been fully delivered and the needle may be removed, or may be premature activation of the security mechanism.

[0048]图6A及6B以剖面图显示于激活后的该自动注入器，该幅视图是从图5所示视回以轴线为中心旋转90度。 [0048] Figures 6A and 6B is shown on the activation of the automatic injector in a cross-sectional view of a web from the view shown in FIG. 5 is a back view of the axis is rotated 90 degrees.因第一致动弹簧102从其压缩的激励态持续扩展，造成致动机构于远程方向的轴向平移。 First actuation spring 102 due to the continued expansion of the excitation from its compressed state, causing the actuating mechanism in the distal direction axial translation.致动机构的此一激活迫使柱塞200也于远程方向(于影线箭头所示方向)移动，而注射器卡匣20藉释放环236与下壳体平台16A间的接合而实质上维持定位。 This actuating mechanism 200 forces the plunger to activate a remote direction (in the direction indicated by hatched arrow) move, by means of the syringe cartridge 20 to release the engagement between the ring 236 and the lower case 16A and the platform is positioned substantially maintained.下壳体平台16A也可位在下壳体内部的各个位置来限制针头的插入深度。 Internet lower case 16A can be inserted into the bit depth of each lower limiting position inside the needle housing.柱塞200在注射器卡匣20的筒身202内部的远程平移迫使液体，诸如药物治疗从药物腔222，通过针头总成40，及流入使用者体内进行药物递送。 The plunger 200 in the barrel 202 of the syringe cartridge 20 inside the remote translational force the liquid, such as a drug from the drug treatment chamber 222, through the needle assembly 40, and flows into the user in vivo drug delivery.组件的尺寸与在该装置内部的轴向行进长度经组配，使得第一致动终端片104的凸部104D恰在柱塞封800接触针头总成40的针头封之前或与其同时，到达下壳体16的内部凹部16D，有效地确保柱塞封800的凹部已经接合式抓住该针头总成40的针头本体的节段425用于回缩，且在该伸缩机构的激活之前。 The axial size of the assembly inside the length of travel through the apparatus constitution, the convex portion such that the first actuation member 104 104D seal 800 just contacts the plunger assembly before the needle of the needle seal 40 or simultaneously with, the arrival inside the recess 16D of the housing 16, to ensure effective sealing of the plunger 800 engages the recessed portion has the formula grasp needle assembly 40 of needle body 425 for retraction of the segments, and before the activation of the telescopic mechanism.另外，内部凹部可定位在上壳体的各点，或在统一壳体内部，但以图6A及6B所示实施例所述相同方式发挥功能。 Further, inside of the concave portion may be positioned at various points on the housing, or inside the housing in a unified, but the embodiment shown in FIGS. 6A and 6B of the embodiment functions in the same manner.同理，内部凹部可改变在上壳体与下壳体间的内部直径。 Similarly, inside the recess in the inner diameter may vary between the housing and the lower housing.于此阶段，许可第一致动终端片104的凸部104D径向地向外弹出进入下壳体16的内部凹部16D内(于藉图3B实心箭头所示方向)。 At this stage, the license first actuating protrusion 104D of the terminal plate 104 to spring outward radially into the inside of the concave portion 16D of the lower case 16 (in a direction indicated by solid arrows in FIG. 3B).此项动作许可第一致动终端片104的连接器叉104B从第二致动终端片108的连接桥108B脱离，因而致动第二致动终端片的功能。 This operation permit first actuation plate 104 of the connector prongs 104B from the second actuation plate 108B 108 bridges disengaged, thereby actuating the second actuating function pill.

[0049]图7以图5的相同剖面视角显示当第二致动终端片被致动时的自动注入器。 [0049] Figure 7 shows the terminal when the second actuation piece is actuated in the same automatic injector perspective sectional view of FIG.如前述，当第一致动终端片104的连接器叉104B从其与第二致动终端片108的连接桥108B的接合释放时，第二致动弹簧106被许可从其压缩的激励态扩展，藉此于远程方向驱使柱塞更为远离。 As described above, when the first actuator is connected to the terminal plate 104 from its fork 104B and the second actuation plate 108B of the engagement releasing the connecting bridge 108, the second actuation spring 106 is expanded from its compressed state licensed excitation of thereby driving further away from the plunger in the distal direction.藉第一致动终端片的导叉104C与上壳体14的锁定凹部14C间的表面交互作用，防止第二致动弹簧106于近端方向驱动该第一致动终端片。 By first actuation fork guide plate 104C of the upper housing 14 of the locking interaction between the surface of the recess portion 14C, to prevent the second spring 106 drives the actuator in the proximal direction of actuation pill.此种组态确保储存在第二致动弹簧106的实质上全部能量是于远程方向释放。 Such a configuration guarantees that substantially all of the energy stored in the second actuation spring 106 is released in the distal direction.第二致动终端片108的功能是确保全部药物治疗皆被递送至使用者及激活针头伸缩机构。 A second actuator movable end piece 108 functions to ensure that all medications are to be delivered to the user and to activate the needle telescopic mechanism.

[0050] 于本发明的至少一个具体例中，针头伸缩大致上类似W02011/075760所述，且将参考图7至图11简短说明如后。 [0050] In at least one embodiment of the present invention, the retractable needle / said substantially similar W02011 075760, and 11 will be briefly explained with reference to FIG. 7 to be described later.于流体内容物的递送期间，柱塞200于图7的影线箭头方向，轴向地移动通过筒身202。 During delivery of the fluid contents of the plunger 200 in the direction of the hatched arrow in FIG. 7, barrel 202 by axially moving.如图9所示，柱塞封800背向抵靠针头封430，而针头封430又背向抵靠射出器600。 9, the plunger seal 800 facing away from the seal against the needle 430, the needle 430 and away from sealing against the ejector 600.此外，射出器环610于图9的实心箭头方向，径向地移动制动器300的臂320A、B的钩端321A、B，藉此将针头本体420从制动器300松脱，来释放针头本体420及套管410用于随后回缩。 Further, the ejector ring 610 in the direction of the solid arrow in FIG. 9, the movable arm 320A radially stopper 300, the hook end 321A B, B, whereby the needle body 420 is released from the stopper 300, the needle body 420 to release and sleeve 410 for subsequent retraction.此时，柱塞封800的凹陷座810具有伸缩型针头本体420的接合节段425，及凹部860具有套管410的接收流体端412。 In this case, the plunger seal holder recess 800 of retractable needle body 810 has engaging sections 420, 425, and the concave portion 860 having a fluid receiving end 412 of the sleeve 410.如此将针头本体420及套管410有效地耦联至210，原因在于柱塞内件210连结至柱塞封800的近端故。 Thus the needle body 420 and the sleeve 410 effectively coupled to 210, because the plunger member 210 coupled to the proximal end 800 of the plunger seal it.

[0051 ]如图7及图10所示，为了让针头本体420及套管410在流体内容物递送结束时回缩，压缩弹簧270必须解压缩，该动作藉柱塞内件210从柱塞外件220脱离之助。 [0051] As shown in FIGS. 7 and 10, in order to allow needle body 420 and the sleeve 410 is retracted at the end of delivery of fluid contents, the compression spring 270 must be decompressed, the motion of the plunger by the plunger member 210 from the outer member 220 from the help.此项脱离是借助于释放环236。 This detachment is released by means of a ring 236.当柱塞内件210及柱塞外件220实质上完全压陷(亦即如影线箭头所示，于远程方向轴向地平移)来从筒身202注射流体时，其中，一者或二者可接触释放环236。 When the plunger 210 and the plunger member within the outer member 220 substantially completely indentation (i.e. as hatched arrows, axially translate in the distal direction) when the barrel to inject fluid 202, wherein one or both release ring 236 may contact.经由此项接触，释放环236移动臂232径向向内(于实心箭头方向)，且从与柱塞外件220的缘部229接合脱离。 By this contacting, the release ring 236 moving the arms 232 radially inwardly (in the direction of the solid arrows) and out of engagement with the edge portion 229 from the outer member 220 of the plunger.此项脱离许可压缩弹簧270解压缩且推向柱塞内件210的凸耳212(显示于图4及图7)来藉此回缩柱塞内件210，具有柱塞封800、针头本体420、及套管410耦接于其上。 Solutions of this license from the compression spring 270 is compressed and the plunger member 210 toward a lug 212 (shown in FIG. 4 and FIG. 7) to thereby retract the plunger 210, the plunger having a seal 800, the needle body 420 , and casing 410 is coupled thereto.柱塞外件220维持实质上接触或连结释放环236，而耦接至针头本体420及套管410的柱塞内件210藉弹簧270的解压缩而于近端方向轴向地平移，藉此回缩套管410及针头本体420。 The plunger is maintained substantially in contact with the outer member 220 or link release ring 236, is coupled to plunger member 420 and the needle body 410 of the sleeve 210 by spring 270 de-compression to translate axially in a proximal direction, whereby the back shrink tubing 410 and needle body 420.图8及图11显示在针头回缩完成后自动注入器的组件。 8 and 11 show the assembly of the automatic injector needle retraction after completion.于此阶段，套管410完全回缩入壳体及/或筒身202内部。 At this stage, the cannula 410 is fully retracted into the housing and / or internal barrel 202.此项针头或套管的回缩乃高度所需，原因在于提供整合型安全结构，同时对使用者提供剂量真正结束的指示。 This retraction of the needle or cannula is the desired height, the reason is to provide integrated security architecture, while the real end user with an indication of the dose.

[0052]适当地，自动注入器100提供一个或多个锁定系统给柱塞200。 [0052] Suitably, the automatic injector 100 provides one or more locking systems 200 to the plunger.如图7、8、及11所示，于该锁定系统的一个具体例中，柱塞200的柱塞外件220包括锁定构件227，其具有边缘228在针头回缩后接合释放环236的底侧237。 7, 8, and 11, in a particular embodiment of the locking system, the plunger 200 of the plunger 220 of the outer member includes a locking member 227 having an edge 228 after needle retraction release ring engaging the side of bottom 236 237.此项接合防止或阻止于近端方向，柱塞200相对于释放环236的进一步移动，如图11所示，同时许可柱塞内件210于近端方向移动。 This engagement prevents or prevents the proximal direction, the plunger 200 moves relative to the release ring 236 is further shown in Figure 11, while the plunger member 210 to permit the proximal direction.因此，除了初始协助针回缩的激活之外，其次释放环236可用来在初次使用之后锁住柱塞200因而防止重复使用。 Thus, in addition to the initial activation of needle retraction assistance, followed by the release ring 236 may be used to lock the plunger 200 after the initial use and thus prevent re-use.如前述，第二致动弹簧作用在柱塞外件本身上的力可额外或另外地防止或「封锁」柱塞外件在致动后于近端方向的轴向移动。 As described above, the second actuation spring force acting on the plunger outer member itself may be additionally or otherwise prevent or "block" in the actuator plunger outer member after the axial movement in the proximal direction.
